The following other options and fields are available on the Batch Process Sub-Products page.
o Add new sub-products
Existing records (if any) are left “as is”. Only new sub-products are added (if any). Use this option if you are creating sub-products for new Apparel products or if you added new options attributes to an Apparel product and need to create the corresponding Sub-Products.
o Update existing and add new sub-products
Existing records are updated with the new settings, and new sub-products are added (if any). Existing sub-products therefore will be affected. They will be updated based on the information entered on the page (e.g. new image name conventions) while new sub-products are added, if there are any.
o Re-create sub-products
Existing records are removed and are re-created. Technically speaking, this means that new records in the store database will be used from now on as Sub-Products for the selected Apparel Products. The existing records are “archived” (they are removed from the Control Panel and the storefront, but remain in the database).
Press the Generate Sub-Products button to start the process. ProductCart will create the Sub-Products and take you to a window that displays them all. You can then verify the field entries and manually edit any of them, if needed.
